1、Section C. Material analysis本课是九年级第一单元第二话题的第三课时，主活动是1a和3b。1a具体了分析中国人口现状的严峻形势和政府采取的措施及成效。这篇阅读文章较长，在阅读练习的时候，建议教师先解决部分生词，扫清单词障碍，1b主要是培养学生找出段落的主旨句的能力。而1c则是要学生学习找到论据。2可以看作是语法巩固训练，但内容仍然紧扣主题。3a和3b是训练说和写的技能的。通过本篇文章的学习，要求学生掌握一定的阅读策略和写作技巧，能够模仿作者恰当运用主旨句的写作方式，排篇布局。引导学生关注社会问题，关注国家政策，培养学生树立良好的人口观念和正确的世界观。.Teachin
